MARTIN M. WILSON, OF HONEY GROVE, TEXAS.

AUTOMATIC TRIP-GEAR FOR POWER-PRESSES.

SPECIFICATION forming part of Letters Patent No, 331,665, dated December 1, 1885.

Application filed July 8, 1885. Serial No. 170,931. (ModeL) To all whom, it may concern.-

Be it known that I, MARTIN MWILsoN, of Honey Grove, in the county of Fannin and State of Texas, have invented a new and useful Improvement in Automatic Trip-Gears for Power-Presses, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a side view, partly in section, of an ordinary power-press having my improved automatic trip attachment; and Fig. 2 is a transverse central section of the same.

In using the ordinary steam-power press it requires the closest attention of the baler in reversing the gearing when the follow-block is operated, as when the bale is taut and is not attended to at the proper time the wings of the screw will strike the nut and are liable to cause a break, and when reversed and going down it will run the wings of the lower end of the screw out of the groovesin the sleeve, thus causing much delay and annoyance in getting it back in position and properly adjusting it.

My improvement consists in providing the lever connected with an ordinary reversible gearing with a cord and weight, so that when in its normal position and not in use the small friction-wheel will not come in contact with either face of the large friction-wheel. The upper end of the press is provided with a notched metallic plate connected with the re versing-lever, so that'when the follow-block in its upward passage passes the said plate the lever will be released, and, falling back into its normal position by the press, is immediately stopped. when it is desired to run the followblock down so asto fold the press,the reversible lever is upheld forward and connected with a trigger at the lower end of the press, which trigger is released when the follow-block nears its lowest point, thus again throwing the lever back centrally by means of the weight, so that the press-screw stops, all of which will now be set forth in detail.

In the accompanying drawings, A represents an ordinary power baling press provided with a usual follow block, B, the screw C, bevel-wheels D, and reversible gearing E. The lever F, operating the reversible gearing E, is designed to be of such a length as to be operated from the platform G at the upper part of the press, and has a cord and weight, H, on

the under side of the platform, the cord extending through a small caster-wheel, I. When the said lever is held in its normal position, as shown by the dotted lines I, by the weight, the reversible gearing E is not in operation, and the follow-block B may be at its upper or lower points within the press.

Within the upper part of the press A, I provide a metallic plate, J, hinged at its lower end through the side of the said press, and provided outwardly with a weight, K, so that when in its normal position the inner face of this said plate J will be flush with the inner face of the press. A hinged lever, L, has a bearing at one end against the upper outer face of this plate J, while the other end projects beyond the outer face of the press, and an arm, M, provided with a series of notches, N, is so disposed-as to connect with the outer end of this lever L,while the other end of this arm M is hinged to the lever F. When the notched end of the arm M connects with the outer end of the lever L, the press being at at this time filled with cotton, and the follow block B at its lowest limit, the upper end of the plate J is pressed inwardly somewhat at an angle, as shown by the dotted lines. In moving the lever F laterally and engaging the notched end of the arm M with the outer end of the lever L, the said lever F is held temporarily in position, thus putting the gearing E in communication, and operating the screw C, so as to raise the follow-block B and compress the cotton, which has previously been placed within the press. VFhen the follow'block B in its upward passage has passed the metallic plate J at the upper part of the press, the end of the lever L, pressing against the metal plate,moves inwardly and releases the notched end of the arm M from the said lever, and the lever F, influenced by the weight, moves forward centrally to its normal position, which throws the device out of gear, thus instantly stopping the screw and follow-block in its upward motion. The lower part of the press is provided laterally with a lever, O, hinged centrally thereto, the forward end of this lever provided with an inturned part, 1?, of such a length that when the follow-block B is lowered it will come in contact therewith. The opposite end of this lever O is provided with a vertical arm, Q, hinged thereto, operating at its upper end through a slot at the forward side of the platform G. d

On the side of the arm Q toward the lever F, I provide an upturned metallic plate, B. When it is desired to lower the follow-block B, after the cotton is compressed, the lever F is pulled forward, as shown by the dotted lines S, when the arm M is hooked by means of the notch T over the upturned metallic plate R, the arm Q, being, however, down, so as to rest beneath this said arm M. When this vertical arm Q is thus down, the inturned wingP of the said lever O is somewhat raised, as shown by the dotted lines U. This forward movement of the lever F to the position as shown by dotted lines S connects the gearing E, thus reversing the screw 0 and follow-block B, which continuesin its downward passage until the lower part of the follow-block B strikes the inturned lug P ofthe lever O, which raising the arm Q, releases the arm M-from the wing R, thus permitting the lever F, by the weight H, to assume its central and normal position, as shown by the dotted lines I,

when the downward passage of the followblock is immediately arrested.

What I claim as new is 1. In an automatic trip-gear for powerpresses, the weighted lever F, connected near its lower end by an arm with the friction-gearing E, the upper end of said leverF having an arm, M, notched at the end, which, when engaging with the hinged lever L, causes the press to run in one direction, and when the said arm is hooked to a projecting wing, R, 0111888 the press to move in an opposite direction, and when said arm is wholly disengaged the weight moves the lever centrally, throwing the device out of gear, all as described.

2. The metallic plate K,hinged through the side of the press, near the top, and weighted at its lower outer end, combined with the hinged lever L and arm M of lever F and the followerblock, whereby the rising follower-block will throw said plate against the side of the press, and thus moving lever L release arm M, allowing the weighted lever F to automatically resume its position, and thus stop the press.

3. In an automatic trip gear for powerpresses, a hinged lever, 0, at the lower part of the frame, one end provided with an inturned lug, P, so that the follow-block B will come in contact therewith, the opposite end of said lever provided with avertical arm, Q, hinged thereto, the upper end of said arm passing through the slot in the platform above, whereby in downward motion the follow-block comes in contact with the int-urned part of the lever, and throws the arm connected with the lever upwardly, and thus releases the forwardly-projecting arm of the weighted operating-lever F, permitting it to assume its nor mal central position, thus stopping the press, substantially as herein set forth.

4. The combination of the press A, the follow-block B, the hinged metallic plate J, the lever L, arm M, lever 0, vertical arm Q, and the weighted operating-lever F, the whole arranged as and for the purpose substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand, this 15th day of June, 1885, in the presence of witnesses.
